Estimate of provinces 18. Estimate of counties 82. 



Latitude 50 — 61. British type of distribution. 



A. A. regions. Inferagrarian — Midarctic zones. 



Descends to tlie coast level, in the Channel. 



Ascends to 800 yards, in E. Highlands (Dickie). 



Eange of mean annual temperature 52 — 39. 



Native. Paludal, &c. I do not find among my own 

 notes any mention of this species above 400 yards of ele- 

 vation ; but as Professor Dickie indicated it so high as 

 800 yards, I adopt his record as the basis and authority 

 for the altitude, zones, and temperature, here given so 

 much above what are warranted by my own notes. Whe- 

 ther J. nigritellus be correctly referred to J. lamprocarpus, 

 or not so, I must confess much doubt. It is an imper- 

 fectly understood species, if really a distinct one.

Native. Paludal. Either much overlooked, or not a 

 common plant in England ; while in Scotland it would 

 seem to be quite local. In addition to some 30 or more 

 counties of England, it has been reported from those of 

 Kirkcudbright (Mr. G. N. Lloyd), Wigton (Prof. Balfoiu- !), 

 Haddington (Prof. Balfour!), Edinburgh (Mr. Thomas
